mickeyiec Posted November 13, 2007 Share Posted November 13, 2007 I just install the efi pack v4, and try to use it with the vanilla kernel. but when my pc boot, it load the bootloader, then black screen then reboot... If i press F8 and type "mach_kernel.toh" in the bootloader, (it is my patched kernel backup), all is good and leopard run Now, if i press F8 and type "mach_kernel -v" to know what's wrong, always a black screen then reboot = no informations like if the bootloader doesn't "read" the kernel or can't read it Any ideas ? I have an intel duo 2 core on an Asus p5ld2 SE (chipset intel 945) Link to comment Share on other sites More sharing options...

I have an intel duo 2 core on an Asus p5ld2 SE (chipset intel 945) - - assuming all the kernel permissions are OK; you could try to boot w/ the flags: -f -legacy Link to comment Share on other sites More sharing options...
niacine123 Posted November 13, 2007 Share Posted November 13, 2007 I got the same problem here with BadAxe2 motherboard. Permissions are ok. mach_kernel = black screen then reboot. -f -legacy = black screen then reboot. mach_kernel.toh work fine Link to comment Share on other sites More sharing options...
Alwayon Posted November 13, 2007 Share Posted November 13, 2007 That just happened to me this evening .... One possibility is that the EFI boot loader has not in place yet. That's why the machine keeps rebooting over and over when loading vanilla kernel. To verify that your EFI installation is working ... don't press F8 when rebooting, ... watch the screen carefully ... let it boots as it likes If it is working... there must be some "EFI........" and another couple of lines appear right after ..." normal "Darwin" and "Starting Mac OSX" " ... which we always see at the boot time. (You will see this only in a flash ... and then reboot will follows/blank screen) If there is only two line as usual (Darwin & Starting or Loading ?) then the EFI is not in place yet, you may want to repeat the startupfiletool again. Please also make sure that you get it into the right disc and partition number. (I found that sometime the disc number can change when you have more than one HDDs) For me ... one time it is /dev/rdisk1s1 ... and after some BIOS resetting or reboot ... it changed to -> /dev/rdisk0s1. So.. check it before using startupfiletool Hope this helps. Link to comment Share on other sites More sharing options...
davides Posted November 13, 2007 Share Posted November 13, 2007 I there, Had the same problem here, mobo is a Bad Axe2, the problem is that you are using .kext that are patched, try to replace them with non patched one. I used this 2 guide: Digitmemo.com where you find the original vanilla Kext. and this post cleared up the rest: Here Used AppleSMBIS that came with the pc_efi_v40, and I had to remove the AppleIntelCPUPowerManagement.kext because I was getting "Package 0 didn't get an Hpet" while booting Only problem is that now my 2 sata HD are detected as External... one is where I boot from. ciao Davide Link to comment Share on other sites More sharing options...
Peelers Posted November 14, 2007 Share Posted November 14, 2007 For all those who have problem with rebooting try this press f8 when it boot now type is mach_kernel.toh or mach_kernel.patch -s this is get you into single user mode with patched mach_kernel then, do the efi patch etc example cd iamefi ./startupfiletool /dev/rdisk1s1 ./boot_v4 substitute your disk # the reason it keep rebooting is because you are using vanilla kernal and you haven't update the bootload yet. hope this help Link to comment Share on other sites More sharing options...
mickeyiec Posted November 14, 2007 Author Share Posted November 14, 2007 i m always stuck... but now, my hard drive scratch a little before rebooting ! What i have done : i took those original vanilla kext and replace them in my system/library/extension (before i have renamed all the patched kext with *.toh) AppleACPIPlatform.kext AppleAHCIPort.kext AppleHWSensor.kext AppleIntelCPUPowerManagement.kext AppleIntelIntegratedFramebuffer.kext AppleVIA.kext IOAHCIFamily.kext IOATAFamily.kext IOHDIXController.kext IONetworkingFamily.kext i have placed the AppleSMBIOS.kext from the pc_efi_v40 pack and a dsmos.kext next i did sudo chmod -R 755 /System/Library/Extensions/* sudo chown -R root:wheel /System/Library/Extensions/* i ve deleted /System/Library/Extensions.mkext i suppose efiv4 is installed correctely. what 's wrong ? always black screen but rebooting 5 seconds after bootloader (before, rebooting after only a second) is there any troubles with Nvinject and my graphique card ? (nvidia) is there any custom setting with my mother board ? What i did wrong ? Link to comment Share on other sites More sharing options...
Peelers Posted November 14, 2007 Share Posted November 14, 2007 it might be your ionetworkingfamily.kext DO NOT use that with a patched applebcm5751eithernet.kext it will cause rebooting everytime Link to comment Share on other sites More sharing options...
davides Posted November 14, 2007 Share Posted November 14, 2007 Another thing I did is to umount the Leopard Partition before doing the: ./startupfiletool /dev/rdisk1s1 ./boot_v4 ciao Davide Link to comment Share on other sites More sharing options...
niacine123 Posted November 14, 2007 Share Posted November 14, 2007 umount partition before apply the efi patch work for me. Thank You! I got Blank Model in GeekBench now. Link to comment Share on other sites More sharing options...
mickeyiec Posted November 16, 2007 Author Share Posted November 16, 2007 Thanks to all ! but all i done was good ! the bios of my mother board was just too old ! i upgrade of it, now it is working ! i m happy ! Link to comment Share on other sites More sharing options...
Scrizz Posted November 16, 2007 Share Posted November 16, 2007 my bios is only a month old......and it still reboots....... Link to comment Share on other sites More sharing options...
Dark_Elf Posted November 16, 2007 Share Posted November 16, 2007 I have updated my bios to the last version (I have an Asrock Conroe945G-DVI). EFI works, but if I try vanilla kernel the system reboots Link to comment Share on other sites More sharing options...
David Chen Posted November 20, 2007 Share Posted November 20, 2007 I also have this issue. But, upgrade BIOS will cause original patched Leopard partition booting fail. So, I can only use an old version. (I am using Asrock Conroe 1333 DVI/H R2.0. I try several version of bios. only 1.50 and below are OK for boot MacOS (patched kernel). 1.60, 1.70 and 2.00 won't work.) It seems this is related to the compatibility between BIOS and EFI loader. Hope it can be fixed soon. Link to comment Share on other sites More sharing options...
XanthraX Posted November 20, 2007 Share Posted November 20, 2007 I also got restarts after boot, I repeated this with boot_v3 and all working fine. Maybe helps. Link to comment Share on other sites More sharing options...
netkas Posted November 21, 2007 Share Posted November 21, 2007 too all who has reboot on core 2 duo and intel-based mobo - check No Execute (NX/XD) enabled in bios, otherwise vanilla kernel will reboot immideatly Link to comment Share on other sites More sharing options...
Scrizz Posted November 21, 2007 Share Posted November 21, 2007 thx netkas will try too all who has reboot on core 2 duo and intel-based mobo - check No Execute (NX/XD) enabled in bios, otherwise vanilla kernel will reboot immideatlyholy :glare: that was it!thx man Link to comment Share on other sites More sharing options...
David Chen Posted November 21, 2007 Share Posted November 21, 2007 Yes. After enable No Execute (NX/XD) in BIOS, EFI works. I think this should be included in EFI installation guide. Thanks. Link to comment Share on other sites More sharing options...
